PETER GERING, a citizen of the Unite'd'States, residing at Schrag, in the county of Adams and State of Washington, have invented certain new and useful Improvementsin Spark-Adjustlowing is a specification.

Other objectsand advantages of my in-- vention Will-become more fully apparent from the; following description Referring to t ne' accompanyingdrawings:

' Figure 1' shows partof anexplos ve engine 'in its state of rest with the spark retarded for startingighig, 2 is a similar vi'ew'with the spark advanced automatically during "the running-of the engine at a-high rate of sleeve 15 which is connected to. the, blades,

collar 15 and regulates theexpansion of the spring-17. A'rod 19 issecured to the collar 15 and is attached to a rod 22 as shown at 23. Said rod 22 is secured to a spark regulating lever24 which is also-connected at25 to a,-

lever 26 which is connectedin turn toe throttle valve of the engine which is placed v in the inlet pipe 27.. Theflmanu'el connec tions for hperating' the throttle valve are 1 so mounted on the steering postof the machine in the customary manner.

" .When the engine- 1s in its state Orleans spark lever at 2d is in theposition shown in Fig. 1. As soon as the! engine is started the'sheft 10 is revolved-and thecentrifagel lever would.- be operated 'to set the. spark and throttle at the desired place forstarting whereupon, after the engine had begunto' moved toward theright and is thrown initsvertical position, shown in Fig. 2. By this the sparle'at 24: with the steering gear, is

gained by the engine the farther..\vill the control the working of the entire engine from one lever controlling the gas throttle gins to'a desired degree, by operating a coin ln-ncd throttle and spark lever on the steermg post. Such-combined throttle and spark run on its own power, the 't hjrottl'e and'spark vonld be'automatica-lly advanced-by 'the action of. the fHILQS'PI'fiV'lOIlSlY described.

when, however, is desired to slow the enginc, the combined control lever just men- 'spring 17. in opposition to the action of the fan blades and thus throw the throttle .and sparker' in position for slow running.-
